Change the potential difference 2 of 8 Voltmeter Measures potential difference 3 of 8 Potential difference Measures the energy transferred to a component for each energy of charge that passes through the component 4 of 8 Resistance Measuring how hard it is for electricity to flow 5 of 8 The higher the resistance... The smaller the current 6 of 8 Diode Conducts electricity in one direction only 7 of 8 What happens in a wire? The flow of electrons in a metal collide with ions in a lattice, and transfer energy to them 8 of 8
